For example, the IEEE 802.11ad Specification defines a 60 GHz system with a single channel bandwidth (BW) of 2.16 GHz, which is to be used by all Stations (STAs) for both transmission and reception.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more mechanisms, which may, for example, enable to extend a single-channel BW scheme, e.g., a scheme in accordance with the IEEE 802.11ad Specification or any other scheme, for higher data rates and/or increased capabilities, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more channel bonding mechanisms, which may, for example, support communication over bonded channels.

In some demonstrative embodiments, the Channel bonding may include, for example, a mechanism and/or an operation whereby two or more channels can be combined, e.g., for a higher bandwidth of packet transmission, for example, to enable achieving higher data rates, e.g., when compared to transmissions over a single channel.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more channel bonding mechanisms, which may for example, support an increased channel bandwidth, for example, a channel BW of 4.32 GHz, a channel BW of 6.48 GHz, and/or any other additional or alternative channel BW.

Some specifications, e.g., an IEEE 802.11ad Specification, may be configured to support a Single User (SU) system, in which a Station (STA) cannot transmit frames to more than a single STA at a time. Such Specifications may not be able, for example, to support transmission from a STA to multiple STAs simultaneously, for example, using a multi-user MIMO (MU-MIMO) scheme, e.g., a downlink (DL) MU-MIMO, or any other MU scheme.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more Multi-User (MU) mechanisms. For example, devices 102 and/or 140 may be configured to implement one or more MU mechanisms, which may be configured to enable MU communication.

In one example, devices 102 and/or 140 may be configured to implement one or more MU mechanisms, which may be configured to enable, for example, MU communication of Downlink (DL) frames using a Multiple-Input-Multiple-Output (MIMO) scheme, for example, between a device, e.g., device 102, and a plurality of devices, e.g., including device 140 and/or one or more other devices.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement any other additional or alternative MU mechanism, e.g., to communicated MU transmissions, and/or any other MIMO mechanism, e.g., to communicate MIMO transmissions.

In some demonstrative embodiments, a communication scheme may be configured to include changes to an existing standard, for example, a legacy standard, e.g., the IEEE 802.11ad standard, for example, in a Physical layer (PHY) and/or a Media Access Control (MAC) layer, e.g., to support channel bonding and/or MU capabilities, e.g., as described below.

In other embodiments, a new and/or independent communication scheme may include a PHY layer and/or MAC layer and/or any other layer, which may be configured to support channel bonding and/or MU capabilities, e.g., as described below.

In some demonstrative embodiments, a configuration of a Physical Layer (PHY) header in accordance with the IEEE 802.11ad Specifications may not be suitable, for example, at least to support MU capabilities and/or channel bonding capabilities.

FIG. 2 is a schematic illustration of a Single Carrier (SC) Physical Layer (PHY) header 200. For example, the SC PHY header of FIG. 2 may be communicated in accordance with the IEEE 802.11ad-2012 Specification.

In some demonstrative embodiments, header 200 may include a scrambler initialization field 202, an MCS field 204, a length field 206, an Additional PPDU field 208, a packet type field 210, a training length field 212, an aggregation field 214, a beam tracking request field 216, a last Received Signal Strength Indication (RSSI) field 218, a turnaround field 220, a reserved field 222, and/or a Header Check Sequence (HCS) field 224. In other embodiments, header 200 may include any other additional or alternative fields.

In some demonstrative embodiments, the PHY header according to the IEEE 802.11ad-2012 Specification may not be capable, for example, of at least indicating to multiple STAs to which STA a Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU) is to be addressed, e.g., as part of a MU transmission.

In some demonstrative embodiments, spatial streams of a transmission, for example a MU MIMO transmission, may be assigned to different STAs, for example, in opposed to the SU transmission supported by the IEEE 802.11ad-2012 Specification.

Accordingly, in some demonstrative embodiments, additional signaling may be configured, for example, to support transmission of spatial streams to different STAs, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to use a header, for example, a PHY header, which may be configured to provide header signaling, e.g., PHY header signaling, for example, modified, new, and/or enhanced header signaling, which may be configured to accommodate frame transmission to multiple stations, for example, using DL MU MIMO, e.g., as described below.

In some demonstrative embodiments, the configuration of a header, for example, a PHY header, may be enhanced, changed, updated, reconfigured, and/or amended, for example, to support MU capabilities and/or channel bonding capabilities.

In other embodiments, a header, e.g., a PHY header, of any other Specification may be enhanced, changed, and/or amended, and/or a new header structure, e.g., a new PHY header structure, may be defined, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate over a Next Generation 60 GHz (NG60) network, an Extended DMG (EDMG) network, and/or any other network over any other frequency band.

In some demonstrative embodiments, controller 124 may be configured to cause a wireless station, for example, a wireless station implemented by device 102, to generate a frame including a header portion and a data portion, e.g., as described below. For example, controller 124 may cause message processor 128 and/or radio 114 to generate and/or transmit the frame.

In some demonstrative embodiments, controller 154 may be configured to cause a wireless station, for example, a wireless station implemented by device 140, to process a received frame including a header portion and a data portion, e.g., as described below. For example, controller 154 may cause message processor 158 and/or radio 114 to process reception of the frame.

In some demonstrative embodiments, the header portion may include, for example, a PHY header, e.g., as described below.

In some demonstrative embodiments, the header portion may be configured, for example, to indicate whether or nor one or more headers are to be included within the header portion, for example, one or more headers to indicate a MU transmission, e.g., MU-MIMO operation, and/or channel bonding, e.g., as described below.

In some demonstrative embodiments, the header portion, for example, a PHY header, may be configured to use a channel bitmap, which may be configured, for example, to indicate a plurality of channels, for example, a set of channels, e.g., contiguous and/or non-contiguous channels, which may be bonded, for example, to communicate a PPDU (“the current PPDU”) including the header portion, e.g., as described below.

In some demonstrative embodiments, the header portion, for example, a PHY header, may be configured to include a channel number corresponding to a primary channel that a Basic Service Set (BSS) may be currently operating on. This configuration may enable, for example, to provide an implicit indication in the current PPDU of the number of contiguous channels that are to be bonded, e.g., as described below.

In some demonstrative embodiments, the indication of two or more channels to be bonded may be included in a non-legacy header, for example, non-legacy header 310, e.g., as described below.

In other embodiments, the indication of two or more channels to be bonded may be included in any other non-legacy header, in any other element of header portion 306, and/or in any other element of frame 300.

In some demonstrative embodiments, according to a first scheme (“Option A”), non-legacy header 310 may include a Channel Bitmap field 360, for example, if channel bonding is to be applied.

In some demonstrative embodiments, channel bitmap field 360 may be included in non-legacy header 310, for example, when the Channel Bonding subfield, e.g., subfield 432 (FIG. 3) or subfield 532 (FIG. 5), includes a value, e.g., “1”, to indicate that channel bonding is to be used.

In some demonstrative embodiments, channel bitmap field 360 may be absent from non-legacy header 310, for example, when the Channel Bonding subfield, e.g., subfield 432 (FIG. 3) or subfield 532 (FIG. 5), includes a value, e.g., “0”, to indicate that channel bonding is not to be used.

In some demonstrative embodiments, channel bitmap field 360 may include, for example, 1 bit octet, e.g., corresponding to eight channels, or any other number of bits corresponding to any other number of channels.

For example, a bit of the sequence of bits may be set to have a value to indicate whether or not a respective channel of the plurality of channels is to be bonded.

In some demonstrative embodiments, a bit in the channel bitmap 360, e.g., each bit in the bitmap 360, may be configured to represent one channel.

In some demonstrative embodiments, a wireless station, for example, a wireless station implemented by device 102 (FIG. 1), which is to generate and/or transmit a PPDU, e.g., according to frame structure 300, may be configured to set a value in a bit location of bitmap 360 to indicate whether or not a channel corresponding to the bit location is to be bonded.

In some demonstrative embodiments, a wireless station, for example, a wireless station implemented by device 102 (FIG. 1), which is to generate and/or transmit a PPDU, e.g., according to frame structure 300, may be configured to set the bit location of bitmap 360 to a first value, e.g., “1”, to indicate that the channel corresponding to the bit location is to be bonded.

In some demonstrative embodiments, a wireless station, for example, a wireless station implemented by device 102 (FIG. 1), which is to generate and/or transmit a PPDU, e.g., according to frame structure 300, may be configured to set the bit location of bitmap 360 to a second value, e.g., “0”, to indicate that the channel corresponding to the bit location is not to be bonded.

In one example, a wireless station, for example, a wireless station implemented by device 102 (FIG. 1), which is to generate and/or transmit a PPDU, e.g., according to frame structure 300, may be configured to set a sequence of “10000001” in the Channel Bitmap 360, for example, to indicate that the first and eighth channels are to be bonded.

In some demonstrative embodiments, the channel bitmap field 360 may be configured to enable, for example, bonding of two or more contiguous channels and/or two or more non-contiguous channels.

In some demonstrative embodiments, according to a second scheme (“Option B”), non-legacy header 360 may include one or more information fields, for example, a primary channel field 370 and/or a channel bandwidth (CH_BW) field 372, for example, if channel bonding is to be applied.

In some demonstrative embodiments, primary channel field 370 and/or channel BW field 372 may be included in non-legacy header 310, for example, when the Channel Bonding subfield, e.g., subfield 432 (FIG. 3) or subfield 532 (FIG. 5), includes a value, e.g., “1”, to indicate that channel bonding is to be used.

In some demonstrative embodiments, primary channel field 370 and/or channel BW field 372 may be absent from non-legacy header 310, for example, when the Channel Bonding subfield, e.g., subfield 432 (FIG. 3) or subfield 532 (FIG. 5), includes a value, e.g., “0”, to indicate that channel bonding is not to be used.

In some demonstrative embodiments, a CH_BW field 372 may be configured to indicate a bandwidth of a bonded channel

In some demonstrative embodiments, primary channel field 370 may include, for example, a channel number corresponding to a primary channel, for example, that a BSS may be currently operating on, or any other primary channel of a network.

In some demonstrative embodiments, a CH_BW field 372 may be configured, for example, to indicate a number of contiguous channels to be bonded.

For example, a receiving STA, e.g., device 140 (FIG. 1), which receives a transmission, e.g., frame 300, including the CH_BW field 372, may be configured to determine a number of channels to be bonded, for example, by dividing the value in the CH_BW field 372 by a bandwidth value of a single channel bandwidth, for example, a predefined channel bandwidth, e.g., as may be used in a NG60 network or in any other network. The number obtained as a result of the division may be the number of channels to be bonded. For example, the result of dividing the value in the CH_BW field 362 by the value of a single channel bandwidth may be the number of secondary channels to be bonded, e.g., starting from (and including), a primary channel indicated by the Primary Channel field 370.

In some demonstrative embodiments, the Option B scheme may be applicable, for example, for contiguous channel bonding.
